Solution 1Recommended

Cancel the Additional 200 GB Storage Subscription

Verify your current storage usage and safely remove the unneeded 200 GB add-on plan through the Microsoft account dashboard.

Because your current file usage is only 300 GB, it falls well below the standard 1 TB storage limit included with your main Microsoft 365 subscription. This means you will not lose any files or data by canceling the supplementary 200 GB plan.

Typically, when you cancel an add-on subscription, the extra storage remains available to you until the end of your current billing period. Once it expires, your maximum capacity will simply revert to 1 TB.

Verify Total Storage Usage

Go to the OneDrive website, sign in, and look at the bottom left corner of the screen to confirm your usage is currently at 300 GB (or safely below 1 TB).

Access Services & Subscriptions

Navigate to the Microsoft Account Dashboard (account.microsoft.com) and click on the 'Services & subscriptions' tab at the top of the page.

Locate the 200 GB Add-on

Scroll through your active plans until you find the specific 200 GB OneDrive storage subscription that is billed separately from your main Microsoft 365 plan.

Cancel the Subscription

Click 'Manage' next to the 200 GB plan, choose 'Cancel subscription', and follow the on-screen prompts to confirm the cancellation. Note the expiration date provided during this process.

Cancel the Additional 200 GB Storage Subscription

Files Remain Safe: Your files are completely safe. As long as your total data stays under 1 TB, OneDrive will continue to sync and store your files normally after the 200 GB plan is removed.

Frequently Asked Questions

What happens to my files if my storage exceeds the remaining limit after canceling?

If your total usage exceeds the 1 TB limit after the 200 GB plan expires, your existing files will not be deleted, but your OneDrive will become read-only. You won't be able to upload, sync, or edit files until you delete enough data to fall back under the 1 TB threshold.

Will I get a refund if I cancel my Microsoft storage subscription early?

Depending on your region and the exact timing of your cancellation, Microsoft may offer a prorated refund during the cancellation process. In most cases, the storage simply remains active until the end of the current billing cycle.

Does the 1 TB storage limit apply to all users in a Microsoft 365 Family plan?

If you have a Microsoft 365 Family plan, each user (up to 6 people) gets their own individual 1 TB of OneDrive storage. Storage is not pooled, meaning your 300 GB usage does not impact the 1 TB allowance of other family members.
